Throw Away Your To-Do List Question

I watched the Throw Away Your To-Do List webinar and am wondering about starting out in the process. My to-do list right now is longer than I can calendar in a single week. If I throw it away, I would be holding all the un-calendared to-dos for the whole week in my mind just to re-download them the next week. How do you recommend handling this in the early rounds of the weekly calendaring process? Thanks!
